Hi,
I read this thread and see no resolve in the matter. I've experienced the same problem. I've unzipped the bundle and it contains many folders/files, none with a "rt_hybrid_j15-bundle.zip"
Did you ever successfully install the bundle? If so, how?? 
Thanks!
Jessie

Hi David,
I must really be doing something wrong! When I click on Download for the Hybrid Bundle, it downloads a folder containing many other folders and files. None of which contain a rt_hybrid_j15-bundle.zip
I have also tried with the Hybrid RocketLauncher (as I would like to use this ... I remember finding this useful with the Dominator template).
This is driving me nuts!
Regards,
PS. I'm using a Mac, is this why?
